Bad service at kagiso mall she'll

Since I been a loyal customer at shell filling station from 2014 I had never received a bad service like it happened today at kagiso mall she'll garage, I believe she'll must train the staff there, I received very bad service when I come there the guy switch off the pressure and tell me he can't help, even I tell him I have emergency my tire is flat his response was he don't care even if I can tell his bosses if I remember we'll his name was Walter
